STM32F103C8 конвертер TTL Serial в CAN ModBus (Converter Module 3.3V-5V)
TTL Serial to CAN ModBus CAN Transparent Transmission Serial Converter Module 3.3V/5V
Product Features
This module is a module that converts a TTL signal into a CAN
signal. The serial port is used as the interface of the embedded
system, the data transmission is simple, there is no need to learn
the CAN protocol, the development cycle is shortened, and the
development cost is reduced. The module is compatible with 3.3V, 5V
power supply, and the small area is semi-hole technology, which is
easier to embed in the system.
The module is equipped with a 32-bit ARM processor and a CAN level
shifting chip. 14 sets of masking filters, each with five frame
filtering methods. The parameter is set to the AT command setting
mode, the command is simple and concise, and there are only 6
instructions. A wider baud rate range is more adaptable to the
network.
Product Parameters
The ARM processor with Cortex M3 core has stronger data processing
capability and lower power consumption. The processor integrates
the CAN controller to make the transmission more time-saving.
5V, 3.3V power supply, LDO linear regulator
CAN baud rate range: 3Kbps--1Mbps fully supports CAN bus 2.0A and
2.0B specifications
Serial port baud rate range: 4800bps--460800bps
The sampling point is automatically adjusted to or close to the CIA
value
Offline self-recovery
14 sets of 32-bit shielding filters, free to choose, arbitrarily
set
The parameter can be set by AT command and saved after power
down.
Data transfer speed: > 600 frames per second
Hardware and software restore default parameters
The message data length 0-8 bytes can be arbitrarily set.
With surge protection circuit to suppress transient interference
and protect internal circuits
Instructions for Use
The serial port of this module is TTL 3.3V signal, which cannot be
connected with 232 signal! If you want to interface with a 5V
system, it is best to have a 5V to 3.3V circuit.
The module has a status indicator that is 1 Hz when in
communication mode and 5 Hz when in configuration mode.
Pin Description
Converter Module
5V: Connect 5V power supply
3.3V: Connect to 3.3V power supply
GND: power ground
CFG: Configuration pin, 0 is the configuration mode, 1 is the
working mode.
TXD: Connect the RXD pin of the target board
RXD: Connect the TXD pin of the target board
CANL: CANL signal line connected to CAN network
CANH: CANH signal line connecting CAN network
Restore default parameter function method
Method 1:
First pull the CFG pin of the module low, and then pull down the
module's indicator light to flash at 5Hz. Then open the parameter
setting software, configure the baud rate of the serial port, and
then click the button to read the parameters successfully, then
click the button. When all parameters are read again, the
parameters will all be restored to the values in the above table.
The serial port baud rate is 115200 at the factory. If it has been
changed and is forgotten, it can only be recovered by Method 2.
Method 2:
This method can only be used if Method 1 fails. Power off first,
short the RT interface on the module (as shown below), and then
power on again. The RT interface cannot be shorted all the time.
Otherwise, the parameters will be restored to the default values
each time the power is turned on.
